                  footprint in line with its decarbonisation strategy and
                  strategic production cost reduction initiatives

Cobus Loots, CEO of Pan African, commented: “Pan African has an excellent track record of successfully commissioning and operating surface tailings retreatment operations, as evidenced by our BTRP, ETRP and Elikhulu operations. As originally anticipated, the Mogale Gold DFS has demonstrated a compelling Project, both operationally and financially. Mintails has the potential to further improve the Group’s overall AISC, while increased annual production will move Pan African further up the ranks of mid-tier gold producers.

Additionally, our re-mining activities will assist with environmental remediation in this area. We look forward to working with all stakeholders to further progress the Project in the months ahead.”

Background to the Project

In November 2020, Pan African announced that the Company had entered into conditional sale of shares agreements to acquire the share capital and associated shareholder loans and other claims of Mogale Gold and Mintails’ SA Soweto Cluster Proprietary Limited (“MSC”) (together the “Mintails Transaction”). Both Mogale Gold and MSC are 100% owned by Mintails SA, which was placed into provisional liquidation during 2018.

The deadline for fulfilment of the conditions to conclude the Mintails Transaction was extended to August 2022 and included the completion of a fatal flaw analysis, prefeasibility study (“PFS”) and DFS. The PFS on the Mogale Gold TSFs was completed during July 2021, followed by the DFS, announced today. Both studies were led by DRA. Further technical work on the MSC TSFs is currently in progress.  

Mineral Reserves and Resources

Following the initial due diligence on Mogale Gold, the following work was undertaken to improve the Mineral Resource confidence:

    --  a highly accurate Light Detection and Ranging (“LIDAR”) survey of the
        entire project area to ascertain available tonnages;
    --  twinning 25 of the historical holes in order to verify grades previously
        reported; and
    --  drilled 82 new boreholes in areas with sparse or no data.

The combined drilling totaled 2,761m resulting in 1,877 samples and 187 control samples; and resulted in the remodeling of all available resources as reported in the Mineral Resource table below:

The updated three-dimensional Mineral Resource models were subjected to a hydro-mining and load-and-haul mine design and schedule according to engineering parameters as defined in the DFS. The same approach was previously used by Pan African during the design process of the Group’s Elikhulu operation (Elikhulu).

Scheduling of the available resources was built around achieving a throughput rate of 800ktpm, as detailed in the July 2021 PFS, as the optimal processing throughput. The Mineral Resources subjected to the mine design and scheduling was subsequently converted to Probable Mineral Reserves, as depicted in the table below:

        scheduled to access remaining Indicated Mineral Resources. The Inferred
        Mineral Resource represents 3.75% of the total Mineral Reserve and is
        not deemed a significant risk
    --  The Mineral Reserve is signed-off by PAR’s Competent Person, Hendrik

Conceptual MSC resource/reserve and production upside

In the SENS announcement of 6 November 2020, the Company reported that the MSC TSFs comprise nine separate facilities with resources of 119Mt with an in-situ grade of 0.31g/t, containing an estimated gold content of 1.20Moz. Although Pan African currently classifies the MSC Mineral Resources in the Inferred Mineral Resource category until further technical studies and work is completed, a conceptual production schedule for this project was applied, based on available information.

This conceptual production scheduling, entailing the processing of combined TSFs demonstrates a more robust recovered ounce profile and an extended LOM for the project, in excess of 20 years. The conceptual MSC TSF model increased production by an average of 11koz/yr from years 6 to 13 (once the Mogale Gold TSF resources are depleted), giving rise to a production profile of an average 54koz/yr from year 14 to 20.

No Mineral Reserves or financial valuation for the conceptual MSC scheduling can be reported on at this stage and the incremental production from this cluster is included for illustrative purposes only.

Re-mining and processing  

The study envisages hydro-mining to be utilised for the larger dumps, using hydraulic guns of similar specification as used at Elikhulu, cutting mine widths of 15m wide and 20m deep. The North Sands and South Sands dumps are conducive to load-and-haul mining, to extract the resources from these dams.

The re-mined tailings will be processed in a CIL plant of similar design to the Elikhulu operation, with the addition of a water treatment section to limit corrosion and potentially improve recoveries. The DFS process plant is designed for an average throughput of 800ktpm, with up to 900ktpm achievable without negatively affecting performance.

All of the borehole samples were utilised to refine and test the expected gold recoveries from the processed material, under the direct supervision and management of Pan African. The modelled recoveries are presented in the table below:
